How This FIPS Code Works

06 093

Census ACS API — Python 06093
import requests

SQL — filtering by county FIPS 06093
-- 5-digit combined FIPS (state + county)
SELECT * FROM your_table WHERE county_fips = '06093';

-- Some datasets store state and county separately
SELECT * FROM your_table
WHERE state_fips = '06'
  AND county_fips = '093';

-- ⚠ Never cast to integer — leading zeros are lost:
-- county_fips = 6093 is WRONG for this county

)
Zero-padding reminder: FIPS codes must always be stored and compared as zero-padded strings. 06 (not 6) and 093 (not 93) — losing the leading zeros is one of the most common data-join bugs in federal datasets. Full guide →
